Wireless routing device, led display controller and led display control system

Abstract

The present invention provides a wireless routing apparatus, an LED display screen controller provided with the wireless routing apparatus, and an LED display screen control system. The LED display screen control system comprises a plurality of the LED display screen controllers, wherein the plurality of the LED display screen controllers comprise a first LED display screen controller and a secondLED display screen controller, the first wireless routing apparatus arranged on the first LED display screen controller ( provided with a 3G / 4G module) works in a routing mode during the operating, and the second wireless routing apparatus arranged on the second LED display screen controller (with no 3G / 4G module) works in a bridging mode during the operating so as to construct wireless bridgingconnection with the first wireless routing apparatus. According to the present invention, the flow cost during the interaction between the LED display screen control system and the server can be reduced, the functions of wireless interconnection and data wireless transmission can be achieved, and the mutual switching between the routing mode and the bridging mode is achieved through the Web management interface.

Description

technical field [0001] The invention relates to the technical field of wireless data transmission, in particular to a wireless routing device, an LED display controller and an LED display control system. Background technique [0002] At present, most industrial-grade routers in the router industry support WDS (WirelessDistribution System, wireless distributed system) function, and the function of WDS is to act as a repeater of the wireless network. By enabling the WDS function on the wireless router, the It can extend the wireless signal to cover a wider and greater range. In short, WDS is a function that allows wireless APs (Access Points) or wireless routers to bridge or relay wirelessly without affecting the coverage of their wireless devices during the bridging or relaying process. . In this way, two wireless devices can be used to establish a WDS trust and communication relationship between them, thereby expanding the coverage of the wireless network to more than doub...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the prior art has the following deficiencies: (1) low-cost wireless data transmission cannot be realized between LED display controllers in the LED display control system; (2) wireless bridging is realized between existing wireless routers It is impossible to access the router Web management interface through IP; and (3) the existing technology cannot realize the function of wireless data forwarding and transmission when the AP and Station functions of the wireless router itself are applied at the same time
